The present invention discloses a roxburgh rose fermented
nutrient solution and an application thereof. A preparation of the roxburgh rose fermented
nutrient solution comprises the following steps: (1) a
raw material treatment is conducted: mature fresh roxburgh rose fruits are selected and washed, the washed roxburgh rose fruits are squeezed into juice, fruit residues are left and taken, the fruit residues are beat, and roxburgh rose fruit
slurry and water are mixed evenly to obtain roxburgh rose
slurry for a standby application; (2) micro-
organism inoculating and fermenting are conducted:
lactic acid bacteria and
saccharomycetes are added for compound
inoculation with an
inoculation amount of 1-5%, and after culturing and fermenting, a
fermentation product is obtained; and (3) micro-
organism removing and filling are conducted: the
fermentation product is centrifuged to extract a supernatant to obtain
fermentation liquid, after the fermentation liquid is filtered with an
ultrafiltration membrane, aseptic
filling in an aseptic environment is conducted to obtain a roxburgh rose fermented
nutrient solution finished product. Vc and SOD in the fermentation product is high in content and also good in stability, and the roxburgh rose fermented
nutrient solution is not liable to brown and stable in product quality, can be used for preparing products with
oxidation resistance and / or high Vc content, such as masks, emulsions, creams, essences, freeze-dried
powder, decoction pieces, capsules, granules or jellies, and has a good market prospect.
